I know quite a lot of Irish people, both over there and over here. And I'm not talking about 1st generation Americans. I'm talking about true Irish people. The Faith is undergoing a massive assault with the modern Irish. My father-in-law was an altar server growing up with the traditional Mass and being educated by cistercians. Now he does not live the Faith, and only goes to the NO, when he goes at all. I've gotten into online arguments in recent months with Irish people because of what was going on with the new abortion laws over there. I finally gave up, realizing what TCat has been saying here to be true, namely that Ireland has lost the Faith.
TCat, I can relate. I got into a lot of fights in my twenties. It's difficult to let go of the feeling of control that you had when most people feared you, but in most cases, it is devils who are coaxing you into losing your cool, so pray not to be tempted. Give control over to Our Lord. You will know when is the right time to fight and when is the wrong time. There is a right time, but it's not so frequent. Christ admonished Peter for cutting off the ear of the Roman soldier. Speak boldly, knowing that you can back up your words with fists if it comes to that, but always speak out of Charity. If someone wants to physically attack you for speaking Truth, then take care of it when that happens. Short of that, I would say that you should hold yourself back from fighting.
